SPECFICATEON forming part of Letters Patent No. 698,791, dated April. 29, 1902.

Application filed April 1, 1901.'

T0 @ZZ whom, it nec/,y concern:

Be it known that I, JOHN BROWN, a citizen of the United States,residing at Norwood,county of Norfolk, State of Massachusetts, (whose post-office address is No. 23 Williams street, Norwood, Massachusetts,) have invented an Improvement in Gluing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like numerals of the drawings representing like parts.

My invention has for its aim the production of a novel machine or apparatus for gluing the facing or covering upon the boards of book-covers; and the invention comprises a suitable support having at one end a gluing mechanism and at the other end a pressing mechanism combined with an endless feedapron, which is adapted to carry the sheets of material which form the facing or covering of the book-covers through and away from the gluing mechanism in order that the said sheets may have glue spread upon one side thereof, and the said feed-apron is also adapted to feed to the presser mechanism, which is preferably in the form of squeeze-rolls, the said glued sheets of material and the backing or the boards of the book-cover to which. the said glued sheets are to be applied, the said presser-rolls pressing the covering or facing rmly upon the boards of the bookcover and causing the same to adhere thereto.

The gluing mechanism comprises a glue-receptacle which is detachably mounted upon a support and the bottom of which is formed by a distributing-roll and a pair of spreading-rolls,'said rolls being mounted for rotation in the support, means being provided to rotate the distributing roll at a dierent speed from the spreading-rolls. Preferably the glue-receptacle will be surrounded by a water-jacket, and means will be provided to heat the water in the j acket,thereby operating to keep the glue warm and in a liquid state.

In the operation of the device the attendant will feed the sheets of material which are to form the facing or covering of the boards of the book-cover to the feed-apron in front of the distributing-roll, and as the sheet is carried by the apron underneath the roll the Serial No. 53,777. v(lilo model.)

said roll deposits a thin film of glue or other adhesive upon the upper face of the sheet of material. As the apron delivers the sheet from the distributing-roll the attendant takes the said sheet and applies the same to the outside faces of the boards of the book-cover, turning in-the sheet around the corners of the book-covers, as usual. The book-cover with the facing thus applied thereto is again placed upon the feed-apron, which delivers it to the presser-rolls, where the facing is firmly pressed and made to adhere to the book-covers, the pressure of the roll causing the facing to be smoothly laid upon the bookcovers.

Referring to the drawings, Figure l is a verticalsection of my machine on the line m Fig. 2. Fig. 2 is a front elevation of the machine with a portion of the glue-receptacle shown in section. Fig. 3 shows the drivingroll for the feed-apron, and Fig. 4 is a detail hereinafter described.

The machine is supported upon any suitable frame or support, said frame comprising the platform 3, having near one end the uprights 4, on which is supported the gluing mechanism, and at the other end suitable upright's 5, in which the pressing mechanism is sustained.

The gluing mechanism comprises the gluereceptacle 6, which extends across the machine and which is preferably detachably secured tothe upper ends of the standards 4L, as by screws 7, (see Fig. 2,) the object in making the said receptacle removable being so that it can be detached from the machine and Y washed Whenever it is necessary to do so. The bottom of the glue-receptacle is formed by the distributing-roll 8 and the pair of spreading-rolls 9, the said spreading-rolls'being arranged one either side of the distributing-roll and contacting with the said roll, the lower edge of the sides of thereceptacle contacting with the upper surface of the spreaderrolls, as seen in Figs. l and 2.

The sheets of material are fed past the gluing mechanism by means of a feed-apron l0, said feed-apron passing around and being driven by a driving-roll 11, which is supported in boxes 12, adjustably mounted in the standards 4. A set-screw 13 is used to adjust roll has mounted thereon a loose pulley 14,v

connected to any source of motive power, and any suitable clutch mechanism may be provided for clutching the loose pulley 14 tothe shaft of the feed-roll 11, said clutch being operated in any suitable way, as by foot-treadle 16. The shaft of the feed-roll has fast thereon a suitable gear 17, which meshes with a gear 18 on the end of the shaft of the distributing-roll 8, (see Fig. 2,) whereby the said distributing-roll is driven from the feed-roll, the gears 17 and 1S being of the same size, so that the surface speed of the feed-apron and the distributing-roll will be the same. The spreading-rolls 9 are driven from the distributing-roll 8 and at a different surface or angular velocity, and for this purpose I preferably provide one end of the said distributingroll with the small gear 20, which meshes with the larger gears 2l on the end of the spreading-rolls 9, by reason of which construction it Will be seen that the rotation of the distributing-roll causes the spreading-rolls to rotate in an opposite direction from said distributing-roll, but at a reduced speed, so that there is a rubbing action between the surfaces of the distributing-rolland thespreading-rolls. The distributing roll, therefore, is allowed to carry down only athin iilm of the glue or other adhesive contained in the receptacle 6, and such thin lm is deposited upon the upper surface of the facing of the sheet of material which is fed to the distributing-roll by the endless apron 10. In order to prevent the said sheet of material from adhering to the distributing-roll and from being lifted off the feed-apron, I have provided a series of yieldably mounted clearing fingers 23, having pointed ends and preferably having at such ends curved surfaces 24, which it the roll, the points of said fingers preventing the sheet of material from adhering to the distributing-roll 8. Oneconvenient Way of mounting these fingers is illustrated in Fig. 1,where in the standards 4 are provided with arms 25, which support a cross-piece 26, having a series of depending arms 26,to which are pivotally connected the said lingers 23, springs 27 being provided to yieldably hold said iingers against the distributing-roll. In order to keep the surface of the roll clean, I have provided the scraper 30, said scraper being illustrated as a bar extending across and contacting with the upper side of the distributing-roll 8 and having the upturned slotted arms 3l at either side, said arms being adjustably secured to the ends of the receptacle 6 by any suitable means, as by bolts 3S. By making the scraper adjustable its constant -contact with the surface of 'a distributingis provided a seriesofrgas-jets 41 for heating the Water in the said chamber, and thus keeping the glue in a liquid state. Pivoted to the lower end of the Water-jacket are win gs 42, said Wings serving to protect the gas-flame and prevent the same from becoming extinguished. A glass gage 43 may be provided, if desired, for readily ascertaining the Waterlevel in the Water-jacket, and an upper opening 44 through the top of the Water-jacket may be provided for the escape of steam.

The upper end of the glue-receptacle has detachably mounted therein a suitable screen 45, in order that as iheglue or other adhesive is poured into the receptacle any lumps or foreign matter may be strained out. v

The presser mechanism comprises two presser-rolls 50 5l, mounted for rotation in the standard 5, the roll 51 being yieldingly held against the fixed roll 50 by the springs 52, the tension of which may be adjusted by the adjusting-screw 53, as usual in devices of this class. f

As stated-above, the feed-apron 10 operates not only to feed the sheets of material to the distributing-roll S, in order that the glue or other adhesive may be applied thereto, but also operates to feed to the presser-rolls the glued sheets andthe backing to which said sheets are to be applied. For thispurpose the feed-apron passes over the guide-roll' 55, down through a slot 56 in the platform 3, over the direction-rolls 57 58, and up through a slot 59 in the platform and over the direction-rolls 60 and 6l, the last roll being Situated adjacent the presser-rolls 50 and 5l, as seen inFig. 1. The apron is then taken over direction-roll 62and down through the platform over rolls 63 64, and thence up throughthe platform and to the driving-roll 1l.

This embodiment of my invention is illus` trated as adaptedto apply the covering or facing to book-covers, and in the operation of the device the attendant feeds the sheetof material Which is to form the facing or covering of the book-cover to the distributingroll 8, with the outside surface of said facing or covering resting upon the feed-apron 10. The distributing-roll operates, as above described, to deposit a thin film of adhesive on' the upper face of said covering or facing. As the apron 10 delivers the glued sheet of material from the distributing-roll the attendant takes the same and applies it to the boards of the book-covers, the edges of the facing being turned in,l as usual, and then the said attendant will deposit the book-covers upon the portion 10' of the feed-apron, the said apron operating to feed the book-covers to the presser-rolls 50 5l, which operate to firmly press the facing or covering onto the boards of the book-cover and cause them to adhere thereto in a smooth condition. As the bookcovers thus nished are delivered from the presser-rolls they drop onto a platform 300, Where they may be removed by an attendant.

By carrying the feed-apron underneath a IOO IIO

portion of the platform, as at 3, I provide a convenient place for the attendant to work in roughly applying the facing or covering to the boards of the book-covers and turning in the edges thereof. n

Any suitable means for driving the presserrolls 50 and 51, which of course are geared together, as usual, may be employed. As one convenient way of accomplishing this, I have shown the lower presser-roll 50 as being belted to the direction-roll 6l by the belt 70.

It is desirable to keep the feed-apron clean, and for this purpose I preferably provide two rotary brushes 7l, which may be driven by means of belts 72 from the direction-rolls 63 and 64.

The apron 10 is illustrated as being composed of a series of parallel endless bands, there being three such bands shown in this instance, l0a l0b l0, and the driving-roll 11 and thedirection-rolls above referred to will each have the annular ribs or s pacin g-iian ges 90 for the purpose of spacing the sections of the feed-apron and guiding the same. The ribs 90 on the driving-roll ll Will preferably project beyond the surface of said roll a distance just equal to or slightly less than the thickness of the feed-apron l0, so that the ribs on said driving-roll Willform with the sections ofthe feed-apron a practically smooth supporting-surface for the sheets of material as they are fed between the feed-apron and distributing-roll.

Preferably the front portion of the platform 3 will be provided with a pocket S0, which is preferably situated directly underneath the driving-roll 11, said pocket serving as a useful place for the placing of any tools that are to be used in connection with the machine.

While I have described my device as particularly adapted to the applying of sheets of facing or covering material to the boards of book-covers, yet it is evident that my invention is not limited to this use, but may be used Whenever it is desired to apply a coating of glue to one face of a sheet of material and then apply said glued sheet to a backing.

Various changes may be made in the structure of the device Without departing from the spirit of my invention, and I therefore reserve the right to make such changes as come within the scope of the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
